PV Array Frame Engineering Certification

Installation of Hopergy Tin Roof Flush Mount Solar System with HOP-SLR0 3 Rails

Gamcorp (Melbourne) Pty Ltd, being Structural Engineers within the meaning of Australian andNew Zealand Building Regulations, have carried out a structural design check of Hopergy Tin Roof Flush Mount Solar System installation within Australia and New Zealand. The design checkhas been based on the information in the schematic drawings of the system components provided by Hopergy Australia (IMSOLAR).

We find the Installation of Hopergy Tin Roof Flush Mount Solar System for Australian and New Zealand use to be structurally sufficient based on the following conditions:

• Wind loads to AS/NZ1170.2:2011 Admt 3:2013• Wind region A, B, C, D, W• Wind terrain category 2 & 3• Wind average recurrence interval of 500 years• Maximum building height 20m• The PV panel dimensions to be 1640mm x 992mm and 2000mm x 1000mm• Maximum weight of the PV panel and array frame to be 15 kg/m2

• Rails to be HOP-SLR03• Rails material to be aluminium graded AL6005-T5 or higher• The tin roof interface to be L-feet bracket or T-feet bracket as per drawing HOP-TRB01-

38• The assessment is based on an assumption that the interface brackets capacity meet

the industrial standard requirements• Each PV panel to be installed using 2 rails minimum in all circumstances• Installation of PV array to be done in accordance with the PV installation manual• The certification excludes assessment of roof structure and PV panels

Refer to attached summary table for interface spacing

NOTES:• The recommended spacing nominated in this certification is based on the

capacity of the array frame, not the roof structure and PV panel. It is the responsibility of the installer to adopt the most critical spacing.
